  You can achieve the same thing with a translate on the plane.

  The problem with using a sphere is that you need to make it really
large and put its origin very far away (below) the camera for it to
look realistic, and objects that large might present rendering artifacts
due to limits in the floating point calculations.

  One common mistake (even present in the povray documentation) is to
center the could sphere at the camera. This, of course, makes no sense
and doesn't even begin to simulate real clouds. Real clouds are not
located on the surface of a sphere centered at the viewer's location.
